PATENT OFFICE- A PARTITION-BLOCK...

.Be it known that I, ADIN G. France, a citizen of the United States, residing in the borou h of Manhattan, city, county,.. and State of ilew York, have invented certain new and useful Improvements in Partition-Blocks, of

which the following the block; 3,an outside face view; Figs.

. A characteristic feature is the making of the block of two halves preferably identical, each half having a portlon or plate formi 0 one of the faces of the complete blockan having projections extending from the face portion, so that when the two halves are rought together these projections se arate ace ortions, so as to form a )OllOW block, an also determine the relative positions of the two halves laterally, so that they may be conveniently held in proper relative positionswhen they are bein cemented together to form the complete b ock.

"Referring to' the drawings, Figs. 1 and 2 show a simple form of block. Each half of the block is designated as a whole by the'lct'ter A, and comprises a face portion B, a lateral pro'ection C for separating the two halves,

an a lateral rojection D, ada ted to overlap' the end o the opposite hal so as to lo cate the halves relatively to each other that is, to determine their relative transverse position. In makin the completed block the two identical ha ves A are brought together in the manner shown in Fig. 1 and cemented at the contacting points. The

identical halves may be very simply molded They are then allowed to harden suiliciently to preserve their shape and placed in juxtaposition and cemented with the greatest ease and rapidity. The half-blocks A may also be provided with grooves E, which serve to engage the ends of the separating projections I thus determining the relative lateral posi- 'tions of the blocks and which provide also lines of easy breakage, so that where a shorter block is desired it' may readily be broken flpeciflcation of Letters Patent.

along the lineF G, Fi 1. The blocks will ordinarily stand with t eir ribs 0 running u and down the wall, and they may be ma e I in considerable lengths with grooves H at brief intervals, (say two inches.) These grooves serve a double purpose of providing eye for the. lastering and of ermitting the blocks to be roken off of an desired le Instead of providing the ocating pro ections at the ends of the halves they may be. provided at other points, as indicated in Fig. 4;, where the projections D serve this purpose and serve also as separating projections, additional separating rojections C being provided at the ends; it 7 ing projections may also be arranged to overngth.

desired. The locatlap at opposite sides, so as to prevent lateral movement in either direction. Such rojeotions are illustrated at D and D 1g. 5.

When the two halves shown in this figure are placed in proper relative positions, there is no lateral movement possi tion. I

For shorter blocks the construction of Fig. plrojection C serving for spacing. and the s oulder D serving in connection with the projection C of the opposing half for locating the blocks latera ly. t

will be seen that with the blocks constructed on the principle described the two halves can be very quickly placed one le in either direc upon the other in proper position and will remam in proper position until the cement sets.

By making the two halves identical a consid'-.

erable economy is obtained. As the blocks can be made of cement of great strength, their walls can be made extremely light. A

prime advantage is the cheapness'of the method of construction of such blocks. The

' ends of the blocks may be hollowed or curved for the rece tion of plaster or cement in erecting the )locks intoa wall. For example, projections H II", Fig. 4, may be rovided at the ends between which is a ho low ture of construction is designed to facilitate the molding of the halves by expressing them in continuous lines from a die and subsequently cutting oiI desired lengths.

Though I have described with great particularit of detail certain specific embodiments 0 the invention, yet it is not to be understood therefrom that the invention is lim- IIO block having a recess E on its inner face op-- site the se arating projection of the other lock,where y to engage the end of such separating projection and to form a line of'easy breakage.
